Embodiment 1

[0037] The peripheral mixer of the present invention is applied in the Isotherming technological process, as image 3 shown. The device capacity can reach 3800bbl / day, and meet the specification of 10ppmw sulfur content in diesel products. Its feedstock is similar to that of many refineries, a 60 / 40 mixture of straight run distillate and LCO, with a sulfur content of about 2,100 ppmw.

[0038] In this process flow, raw oil and supplementary hydrogen are fed into the circumferential mixer at the same time, and the two are uniformly mixed by the function of the circumferential mixer, and at the same time circulated by the circulation pump, and the initial reaction is carried out through the Isotherming reactor, thereby improving the The mixing degree of the hydrogen-dissolved heavy oil entering the hydrogenation reactor.

[0039] As one of the ways to improve the effect of hydrogenation reaction, the device improves the reaction effect of hydrocracking, improves the quality of...

Abstract

The invention relates to a circumferential direction mixer and a gas-liquid / liquid-liquid mixing method using the same, and provides a circumferential direction mixer. The circumferential direction mixer comprises a volute and a circumferential direction fin arranged in the volute; an annular runner used for mixing gas-liquid / liquid-liquid is formed between the volute and the circumferential direction fin. The invention also provides a gas-liquid / liquid-liquid mixing method.

Description

technical field [0001] The invention belongs to the field of gas-liquid or liquid-liquid mixing reaction, and relates to a two-phase mixing method. Specifically, it relates to a method for premixing and reacting hydrogen and heavy oil in the hydrogenation process, and a device used for implementing the method: a circumferential mixer. Background technique [0002] Liquid-phase hydrogenation has many advantages over gas-phase hydrogenation, and it is one of the hot spots in the research and development of petroleum refining at home and abroad. The current oil refining industry has proposed some new ideas and technologies to remove sulfur content that is difficult to remove, and in some oil product specifications, the sulfur content requirement is almost zero. Foreign companies Process Dynamics and LindeBOC Process Plants LLC (LBPP) have developed a new technology IsoTherming (isothermal) through research on the basic principles of hydrodesulfurization in trickle bed reactors...
